“elephant” story is all too familiar, the same five elephants in the perception of the blind, there have been five different judge, and are derived from one-sided, the lack of objective judgment; there is in economics words dedicated to explaining this phenomenon, called “incomplete information.” Incomplete information means that market participants do not have all the knowledge of an economic state of the environment, this has not made up of many factors, such as limiting the cognitive abilities; and it is this information does not fully exist, leading to possible follow-up many of uncertainty risk.
elephant so, the car is also true. Car market of each individual consumer, behind consumer behavior are present incomplete information and uncertain risks; To remedy this market failure as much as possible, so AQSIQ issued a “car three guarantees” policy. But the “three guarantees” just for Consumer Protection set up a threshold, car prices based on the product of confidence, confidence in the brand, “three guarantees” on the basis of the implementation of the extended warranty, consumers digestion is essentially due to incomplete automotive products information leading to the risk of uncertainty, namely to provide consumers with a sense of security.
At present warranty period for domestic car prices, the main push from 3 years or 60,000 km to 100,000 km or four years ranging, there are so-called lifetime warranty; lifetime warranty but must meet a number of preconditions, such as the owner’s first, non-commercial vehicles, cars and other networks about. In the mainstream 100,000 compact SUV, the contrast, the Dongfeng Fengshen models for the 2020-year unlimited mileage warranty period of 10 AX7 provided better digestion consumer uncertainty risk for subsequent use in automotive products; because 2020 models AX7 enjoy the main product warranty covering the automotive product life cycle, both to protect the owners of the replacement process residual rate products, but also protect the interests of subsequent owners.
warranty provided by the major car companies for the “three guarantees” policy of non-consumable product quality consumable parts guaranteed; AX7, paragraph 2020, for example, 10 years enjoyed unlimited mileage warranty, i.e., the first car is turned off to prolong invoice within 10 years (unlimited mileage) for the vehicle, it does not contain the consumable parts and general wearing member repair service. As a pure consumer goods, automobile itself, there is the daily wear and tear due to the use of lead, so in this one-year warranty, higher car prices and consumer concerns are focused on the maintenance costs of parts, namely quality assurance powertrain.
From the consumer standpoint, powertrain maintenance the cost of vehicle maintenance costs are the highest part; while standing car prices stand in the vehicle powertrain manufacturing costs are also the highest proportion of parts, and is the most intensive part of the core technology. Thus, the advantages of the powertrain is Dongfeng Fengshen AX7 provide the courage for the 2020 models emboldened where the 10-year unlimited mileage warranty, because the 2020 models equipped with second-generation AX7 EP6 engine and Aisin third generation 6AT gearbox.

We must first of its profits; powertrain is the primary problem faced by today’s car prices in automotive research and development; as emissions, environmental trends Yuequ harsh competition or internal combustion engine has risen to contest the black technology, how to achieve lower emissions, lower energy consumption and maximize performance, is the common objective of all engineers; which is given jointly BMW and PSA Group engineers answer is EP series engine, full name Prince engine, is also known as the Prince engine.
set the PSA group small-displacement engine with BMW experience the culmination of the engine technology of EP series engines, BMW and PSA Group combines many of the top technology in the production of several years, award-winning, small-displacement turbocharged direct injection engine pioneer product, and its other brands often compared, it is the public. Mounted on the Fengshen AX7 2020 models, is in the first generation EP6 engine on the introduction of the second generation of more black technology products, in addition to six countries to meet emission standards, in energy efficiency, performance has been further enhanced . Then the second-generation EP6 1.6T turbocharged engine has double channel technology which it black?
The lightweight design of the second generation EP6 engine, on the basis of an aluminum alloy cylinder head, the cylinder, the added weight of the hollow piston and the exhaust valve design Waxed; lightweight “Eco Art” structure than the weight of the piston can effectively improve the hardness, enhance the bearing capacity of 30 The percentage above. Further, the DLC coating FSR-K piston skirt and piston pin of the coating, can effectively improve the coefficient of friction of the piston and cylinder wall, enhance the life of the piston.
The continuously variable valve lift technology another name call (BMW Valvetronic), when the engine is operating advantage of the throttle valve remains fully open state, the continuously variable valve lift technology by stepless adjust the feed rate, adjustment logic based on the position of an accelerator pedal; the technology to maximize the benefits the pump intake resistance is reduced, reducing the intake air turbulence, in turn, enhance the intake efficiency, performance and reduce power consumption. According to official reports, equipped with the technology can be increased by 10 percentage -15 percentage of power, fuel consumption reduced by 7 percent, while improving the smooth running of the engine and reduce exhaust emissions.
Continuous intake and exhaust VVT referred technology called DVVT, the technologyDifferent car companies have different names, such as Toyota’s VVTi, Honda’s VTEC, BMW Vanos; this technology can be adjusted with the exhaust valve timing controller through an intake valve timing, intake and exhaust timing is adjusted , to ensure the efficiency of the different optimal gas distribution conditions, so that the engine in the low speed high torque output can be achieved. (Second generation EP6 engine intake timing phase of maximum 70deg; variable angle of crankshaft rotation, the phase of the exhaust valve timing for maximum 60deg; variable angle of the crank angle)
[123 ] between the
single twin-scroll turbochargers conventional single scroll single turbocharger, the biggest difference is more than an exhaust passage, an exhaust gas introduction passage 4 of the cylinder, an exhaust gas introduction passage 3 cylinders; an exhaust gas passage two work together to reduce the exhaust interference, increased impulse supercharging, brought advantage is that compared to ordinary turbo can relieve turbo lag phenomenon, and the peak torque of the engine burst earlier. EP6 turbine engine, i.e., the second generation will intervene in 1000 rpm, 1750 rpm can output 250Nmiddot; m peak torque.
using chain drive timing chain benefits, timing belt has a longer lifespan compared to the more stable performance, more compact, higher transmission efficiency advantages ; because the chain drive chain alloy material, can effectively prevent tooth jump phenomenon occurs, and its alloy, may need maintenance. Second generation timing chain EP6 engine uses a 8-shaped outer link plates, a B-shaped design of the inner link plate, having a weight loss, reducing friction, improving strength and the like advantages of the chain.
Second Generation EP6 electronically controlled engine mounted thermal management system for the PSA Group, exclusive development, this system consists of electronically controlled clutch-type drive water pump and electronic thermostat composition; simple to understand is that when the cold start, the engine does not reach operating temperature, then you can control by electronically controlled clutch the above figure clutch wheel, so that the pump isClosed state and shorten the warm-up time. The effect on the pump system is to achieve open, closed flexible adjustment; or as soon as possible so that the engine reaches operating temperature is always in the best; as for determining the engine temperature is too low or too high a standard, by electronic thermostat play.
In addition to these techniques, the second generation is also a new generation of engines EP6 crankcase ventilation system, the traditional dual turbocharger branch crankcase ventilation system, increasing the gas dilution tunnel , reducing the proportion of the crankcase ventilation exhaust, improving the oil separation effect and reduce carbon deposition.
a meet the country six emission standards, with high efficiency , black & full engine performance in order to be efficiently transmitted to the wheels, so that the car reflects the strength of energy-efficient, strategizing can not do without the gearbox. Dongfeng Fengshen AX7 match for the 2020 models from Aisin Seiko third generation 6AT gearbox, tap platform, blessing upgrade improved from the third generation of Aisin gearbox based on the second generation 6AT transmission, reliability, maturity degree and practicality, in the market can be described as legendary.
Third Generation Aisin transmission by two 6AT the planetary gear shift mechanism to reduce fuel consumption, after the upgrade to the electric oil pump oil pump, can improve fuel efficiency; another highlight of this gearbox is that it is equipped with “quick shift technology” for the driver’s intention comprehend faster, faster. As for reliability and quietness, this is a love letter 6AT strengths, but the third-generation products and further upgrades, such as the transmission of heat dissipation was improved, new growth in travel damper in the torque converter, etc. .
sense of security before consumers buy cars, 2020 models AX7 based on a cost-effective combination of power, providing a 10-year unlimited mileage warranty policy;The safety car during the 2020 models AX7 also not be ignored. 2020 AX7 models using high-strength body technology, 67.7 percent body frame using high strength steel material and ultra high strength steel, Taiji formula star safety body when sufficiently absorbing the collision energy, reduce the damage inside and outside the car, from the foundation of occupants of the cabin to create a safe space.
As for active safety in consumer perceived aspects, 2020 AX7 same paragraph full of black science and technology; for example, by world-renowned supplier TRW custom brake calipers, so 2020 models AX7 have courage not brake the braking performance. In addition, such as AEB Auto Brake Assist, front collision warning system FCW, AEB automatic emergency braking function, BSD blind spot monitoring system, smart technology, models 2020 AX7 think consumers are thinking, one step ahead of security. And all in all, are for 2020 models AX7 is committed to creating a sense of security so that consumers full of cars, and travel experience.

from the car since its inception, despite the growing number of cars carried by the role, from means of transport to the way of life; but the powertrain is still a car prices into the biggest part of the R & D costs , but also consumers are most concerned about car parts. First, because the car’s powertrain as the “heart” status, the second is cost accounting powertrain still account for the largest part of a car, consumers face when the car is also a product of incomplete information, the greatest risk of uncertainty .
2020, paragraph
AX7 as a compact 100 000 SUV, practical, peace of mind and ease of use is the primary demand for cars this positioning customer base, AX7 2020 models equipped with black &Full powertrain, by 10-year unlimited mileage warranty policy for consumers to eliminate insecurity before the car; by a wealth of active and passive safety technology, further digestion uncertain risk of a subsequent user of the car, the occupants personnel to reach practical, peace of mind, easy to use user experience.
